1. INTRODUCTION
This maintenance manual contains of certain information that may result
in fraudulent use. Do not release any part of this manual to any end
users or un-authorized persons.
Ender users should be advised not to undertake any trouble shooting
except those listed on the operation manual.
The internal mini switch should be so set to prevent un-authorized
settings or alternations.
Should a load cell has been replaced, make sure that the protection
devices are properly set.
After servicing, it is necessary to go through all tests and procedures
to ensure the scale meets all the metrological and approval
requirements.

Description:
When an article is placed on the platter, the load of the article is
applied to the load cell inside the scale.
The resistance to the excitation current in the strain gauge will then
changed and the analog output signal varies.
It is amplified and digitized continuously by the A/D converter into
a digital signal. Subsequently, the resulting count is processed and
managed by the CPU. The CPU refers to the instructions from the keyboard,
and then conveys the output data to LCD driver, which formats the data
into readout on the display panels.

4.2 PARTS AND COMPONENTS TROUBLE SHOOTING
4.2.1 Power Supply Checking
4.2.1.1 Relevant parts:
Main Board (M2-10-X,ASK-10-X)
Q1 (A733)
D3 (1N4148)
Q2 (C945)
Q3 (C945)
U3 (2950-5)
DC JACK (SCD-022)
Description:
1) AC Adaptor: This AC Adaptor provides power of DC9~12V,100mA
2) Battery: Battery(9V, 6F22 TYPE)
3) +5V power drives analog/digital circuit system.
U3 (2950-5) is a 5volts Voltage Regulator.
4) Auto-off:
If the scale is set withXX_oFF(Fun-4) or even under LO-BAT situation,
CPU will release a high potential signal to cut Q2 off after setting
time reached. Without E-B biasing, Q1 will be off to shut down
the scale immediately.
5) Low Power Detection:
The Q3 (c945) is designed to detect the power level. When battery
power is less than 5.5V, the collector pole of Q3 will become high
potential level, mean while CPU detects the level changed then
23
CPU will light up LO-BAT indicator on the display.
4.2.1.2 Input voltage: 5.5V or higher
Check and replace battery if voltage less than 5.5V.
Check DC-JACK or AC Adaptor if been defective.
4.2.1.3 System voltage (Vcc): 5V +/- 10%
Check that the system voltage is within 5V +/- 10%
a) less than 4.5V, the CPU may not work properly.
b) more than 6V, it may damage some components .
4.2.2 Platter Stopper Checking
The platter device shall not touch anything around itself during
operation. Check that the platter is not contacted with the upper
(no load) and/or lower (with load) stopper.
4.2.3 LCD Display Checking
4.2.3.1 Check that it is soldered and connected properly between LCD
and CPU.
4.2.3.2 Check whether LCD is broken.
4.2.4 CPU Checking
4.2.4.1 Check that all pins are properly soldered.
4.2.4.2 Check that the Crystal Oscillator works.
4.2.4.3 Check the RESET is normally high.
4.2.5 A/D Unit Checking
4.2.5.1
Check that the +5VA & +5V powers are correctly fed to the
A/D unit.
4.2.5.2
Check that the signal output of loadcell is normal.
4.2.5.3
Check Micro-Controller(SN8P1908).
When no error is found with the above checking procedures, the trouble
can be caused on the loadcell or the PCB itself. Replace a new one
could be better to identify the defective.
In this way, the readout of weight would be varied because of the output
voltage of loadcell and different span value, so re-calibration is
required after this replacement.
